Direct replacement for HP Envy 15-as series

The KingSener VS03XL is a new lithium-ion battery rated at 52WH and 11.55V. It matches part numbers VS03XL, HSTNN-UB6Y, 849047-541, 849313-850 and TPN-I125. The unit fits the Envy 15-as000 through 15-as101ng range listed by the supplier.

Steady output across a full discharge cycle

Rated capacity of 52WH delivers consistent voltage under sustained load rather than a brief peak. Lithium-ion chemistry maintains stable 11.55V output as the charge depletes, supporting typical workloads without sudden voltage sag. The cell is built to specification for reliable daily cycling.

Verify the exact model suffix before ordering

Compatibility covers Envy 15-as models including 15-as001ng, 15-as014wm, 15-as025TU through 15-as032TU and 15-as101ng. Check the label on your current battery for VS03XL or the listed replacement part numbers. This pack will not fit Envy models outside the 15-as series or other HP lines.

Questions about this item

Does the 11.55 V lithium-ion cell generate noticeable heat during all-day use?

The 52 Wh lithium-ion pack runs at standard laptop temperatures; no extra cooling is required beyond the Envy 15-as chassis design.

What must already be in the laptop for this VS03XL to fit and connect?

The battery replaces part numbers VS03XL, HSTNN-UB6Y, 849047-541, 849313-850 and TPN-I125, so the original battery bay and connector must be present.

Will the 52 Wh capacity match the runtime of the original battery in an Envy 15-as025TU?

Yes, the 52 Wh rating and 11.55 V voltage match the factory specification for the 15-as series models listed.
